Begonia plant named ‘KRILOGO01’

ABSTRACT

A new and distinct cultivar of  Begonia  plant named ‘KRILOGO01’ characterized by its upright to outwardly spreading and mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; double-type flowers that are orange in color and held above and beyond the foliar plane; and excellent postproduction longevity.

Botanical designation: Begonia x hiemalis.

Cultivar denomination: ‘KRILOGO01’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia x hiemalis, commercially referred to as an Elatior Begonia and hereinafter referred to by the name ‘KRILOGO01’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Ermelo, The Netherlands. The objective of the breeding program is to create new freely-branching Begonia plants with excellent postproduction longevity and attractive flower color.

The new Begonia plant is a naturally-occurring whole plant mutation of Begonia x hiemalis ‘Reins’, disclosed in U.S. Plant Pat. No. 19,336. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Reina’ in a controlled greenhouse environment in Ermelo, The Netherlands in June, 2016. Asexual reproduction of the new Begonia plant by terminal vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since September, 2016 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KRILOGO01’. These characteristics in combination distinguish ‘KRILOGO01’ as a new and distinct Begonia plant:

-   -   1. Upright to outwardly spreading and mounded plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Double-type flowers that are orange in color and held above         and beyond the foliar plane.     -   7. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the mutation parent, ‘Reina’, primarily in flower color as plants of ‘Reina’ have darker orange-colored flowers than plants of the new Begonia.

Plants of the new Begonia can be compared to plants of Begonia x hiemalis ‘Batik’, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differ primarily from plants of ‘Batik’ in the following characteristics:

-   -   1. Plants of the new Begonia have larger flowers than plants of         ‘Batik’.     -   2. Plants of the new Begonia have double-type flowers whereas         plants of ‘Batik’ have single-type flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘KRILOGO01’ grown in a container.

The photograph on the second sheet are close up views of the upper (right) and lower (left) surfaces of typical leaves and flowers of ‘KRILOGO01’, and in the center of the photograph is a close-up view of typical flower buds.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring and early summer in 12-cm containers in a glass-covered greenhouse in Ermelo, The Netherlands and under cultural practices typical of commercial Begonia production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 18° C. Plants were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
